FIELD OF THE INVENTION

This invention relates generally to a content delivery system and methodfor enabling a user's freedom of mobility while maintaining access to“real-time” on-going content without substantial interruption to thecontent delivery and without requiring user intervention; even as theuser transitions from one physical location where the content isaccessed from multimedia data processing system (referred to as targetdevice herein) on one network environment to the next physical locationwith different target device on a different network environment. Moreparticularly, the present invention improves content delivery between asmart personal device and a plurality of target devices while reducingpower consumption of the devices; and being able to pull desirablecontent from the target devices including but not limited to contentslocated on a single network location, on multiple network locations, andcontent hosts located over the internet.

DESCRIPTION OF THE BACKGROUND ART

Technology has brought us the personal computer (PC), HDTV, Digitalpersonal Multimedia player, Personal Video Recorder, Smart Phone . . .however in our daily interaction with these analog and digital targetdevices we are still limited under the current model of being tied downto the physical location of each of these devices, i.e. the content isalways accessed by user within proximate to the given device whereas thecontents are either stored, displayed, or being sourced from the device.The physical distance limitation restricts a user to sit in front of aPC, sitting around a TV and PVR to watch a TV content, which severelylimits our freedom of mobility especially when a user may have multipleTVs and multiple work environments in one location. The content isdelivered to each physical device by plurality of ways is anotherlimitation in that a HDTV devices can receive contents from Cable,antenna, satellite dish, USB, Ethernet LAN, Wireless LAN. Even whendevices receive content via a similar source, each device would need tobe interface and programmed individually. Another limitation is thatcontents are only accessible on each physical target device with its ownunique user interface or being able to remote controlled. User has tolearn the user interface and or control buttons of each device tooperate from simple turning on and off to gaining access to the contentof a selected device. Another drawback from the current contentaccessing model is wasted energy and bandwidth requirements. Withmultiple target devices around a home or office, we have to turn on adevice when we desire to operate or access the contents upon enteringits surrounding location. Frequently we have these devices turned on inmultiple locations so a user can be mobile from one location to another,using transmission bandwidth for each unit even though a user is nolonger proximate to the device. Another drawback from the currentcontent accessing model is that the content to be access by the user arestore either within these target devices or close by the physical deviceitself i.e. a home entertainment center including a TV, a DVR, a musicsystem . . . etc. As a result, plurality of remote control devices mightbe implemented to provide users with access to content and operationswith all devices located proximate of each other. We are well aware ofthe inconvenience of plurality of remote devices around a givenlocation. The inefficiency in the current model produces undesirableside effects such as in the case of leaving the devices turned on, whichinclude wasted electricity, running up the usage of the devices thusreducing the useful life and dealing with the heat generated by thedevices. In addition, managing multiple user interfaces and remotecontrols for each of the devices is time-consuming and can befrustrating. Another undesirable side effect is the potential ofinterference of these devices on wireless networks amongst each other.One of the disadvantages from the user's perspective is the inherentdeficiency in the physical range limitation of device centered sourcingand control, which prohibits the continuity of operations and contentaccess and delivery when user physically moves from one location toanother.

Accordingly, the prior art systems for delivering and accessing contentfrom these target devices have significant disadvantages andlimitations. It would, therefore, be highly desirable to employ a smartapparatus which can eliminate the problems of the conventional processand allows users to have freedom of mobility while accessing the desiredcontents spanning multiple target devices without interruption andwithout requiring user intervention.

SUMMARY OF THE INVENTION

A smart personal device is a digital Device which can discover,register, activate, deliver content and deactivate of a plurality oftarget devices including but not limited to HDTV, PVR, PMP, PC, DVRaround a home, office, hotel room, conference center as describedherein. The smart personal device can be embedded within a digitaldevice including, but not limited to, a smart phone, a personalcomputer, a laptop, a netbook, a GPS, a personal multimedia player,video MP3 player, a portable radio or a tablet PC.

The smart personal device is used to first discover multiple targetdevices upon identifying one or more target device(s) located proximateto the smart personal device. The present invention uses RFID solutionfor discovering target devices around one or more physical locations,although it is not limited to a specific communication technology in thefuture (i.e. wireless USB, wi-fi, RF, FM, Cable, etc). Once a targetdevice is discovered and registration steps are completed, the targetdevice in one embodiment to be placed in a sleep mode if the targetdevice is not being used by a user or there is no smart personal deviceis in proximate to the target device. Upon the smart personal deviceidentifying one or more target device located proximate to the smartpersonal device and based on the desired state of the smart personaldevice, it will automatically wakeup and activate one or more of thetarget devices and deliver content to the target device to meet the needof the user. These include but not limited to receive and displaycontents from the Personal Smart Device as in the case of a HDTV,receive and play contents from the smart personal device in the case ofa digital speaker system, receive and display contents of an applicationas in the case of a personal computer. When the smart personal device isno longer proximate to the target device, the target device will bedeactivated by the Personal Smart Device and resume its sleep mode.

The present invention is a system and method which overcomes thelimitations and disadvantages of the prior art by providing a simple andconvenient way of allowing a user with freedom of mobility and to movefrom one environment to another while continually accessing his contentwithout interruption.

DETAILED DESCRIPTIONS OF PREFERRED EMBODIMENTS

Before describing the preferred embodiment in detail, a description ofsome of the terms used herein may assist the reader to understand thepresent invention.

-   -   DISCOVERY: The smart personal device enables a user to select a        discovery mode from which the smart personal device will        discover target devices which are capable of being interacted by        the smart personal device. The discovery method currently        contemplated comprises, but is not limited to, using any one or        more of the following: RFID, wireless, powerline, FM, LAN, USB        networking communication media. The preferred embodiment of the        present invention is described in the context of discovering a        RFID device which is built within or associated with each target        device while a smart personal device is located proximate to the        target device. During the discovery process, the smart personal        device initiates all its tasks and performs all functions while        target device can be passive and its main electronics other than        the minimal components may be powered off or in low power sleep        mode other than the minimal functions including but not limited        to the RFID and Wake on LAN or Wake on USB. Once the smart        personal device identifies a suitable target device located        proximate to the smart personal device, it will register the        target device and its functional characteristics such as TV,        HDTV, DVR, Music systems in the smart personal device's        configuration table. The smart personal device at its option,        depending on its programming and user and/or system preferences        and requirements may perform a quick test to confirm the target        device's capability even if the target device is in active        operation without disrupting any user action to confirm the        target device's capability. During the quick test, If the target        device is powered off or in a low power sleep state, the smart        personal device can wake up the target device by using an        industry standard method including but not limited to wake on        LAN or wake on USB method. The smart personal device is capable        to perform rediscovery update operation either upon user's        selection or perform at a fix interval to detect if there is any        new target device since the last discovery operation. If a new        target device is discovered the smart personal device will alert        the user and enable the user to choose to ignore or to add the        newly discovered target device to the configuration table. A        target device may include a configuration option for not be        discovered or only be discovered and registered by if the smart        personal device meets certain parameters including but not        limited to authorize by user, by device type, by password, by        functionality.    -   REGISTRATION or REGISTERING: Upon a successful discovery of a        target device, the smart personal device is capable of        registering relevant characteristic of the target device by        storing in the configuration table of the smart personal device.        The relevant characteristic of the target device may include but        not be limited to brand, model, maker, MAC ID, CPU speed, main        memory size, disk storage size and type, network capability,        smart Direct I/O capability, GPS location, input I/O type,        output I/O type. Once registered, the target device is available        to be woken from a low power sleep state and ready to perform        operation upon command including but not limited to receive and        display content or to transfer content to the smart personal        device. The present invention uses the smart personal device to        perform all the necessary discovery and registration tasks        independent of the target device while the target device is        passive or in a low power sleep mode. In an alternative        embodiment, the discovery and registration steps can be easily        performed with active participation by the smart personal device        and target device. In one embodiment of a related invention the        target device performs the role of Discovery and Registration        whereby the target device identifies a smart personal device        located proximate to the target device and performs all        operations to discover and register the smart personal device        while the smart personal device is passive till the target        device activates the smart personal device.    -   ACTIVATION: Once the smart personal device identifies a target        device located proximate to the smart personal device and        confirms in the configuration table that it is a valid and        registered target device, it will automatically perform a wakeup        commands to the target device without the awareness of the user.        In addition, if the smart personal device is being used by the        user to perform an ongoing live operation including but not        limited to a Windows or MAC or Google application such as word        processing, windows office, playing music, video playback, TV        broadcasting program, internet related operations such as        search, news, blogs, purchase, etc., the smart personal device        will command the target device to instantaneous switch from the        low power sleep state to an active state to perform I/O        operations on the target device. The present invention will        enable the target device, if it's already performing an        operation, to automatically perform a split screen if the target        device includes a display unit and has the split screen        capability. One or more target devices may be activated at the        same time within proximate to the smart personal device, i.e. PC        and printer, HDTV and DVR.    -   DELIVERY CONTENTS: Contents are delivered from the smart        personal device to on e or more target devices via various means        including but not limed to wireless Ethernet 802.11 G/B/N/A, USB        wireless, mobile phone wireless, powerline, RF, FM etc. In one        embodiment of the present invention, the content is delivered        from the smart personal device to the target device using one of        the target device's input unit controllers. If the target device        is a HDTV, the input unit controller is capable of receiving        content from input source including but not limited to antenna,        cable, wireless LAN, RF, FM, LAN, wireless USB. If HDTV        comprises a HDTV Core Media Processor than its CPU, main memory,        output unit controller will be activated to receive the content        from the smart personal device using its input unit controller,        transmit the content to the CPU/main memory using the I/O BUS.        After the CPU process the content, it will transfer the content        to the output unit controller using the I/O BUS and the output        unit controller will display the content on the target device.        In this embodiment, the majority of the digital logic will be        powered to perform the function.    -   In another embodiment, whereas the target device comprising        smart input I/O controller and smart output I/O controller, once        the target device is being activated by the smart personal        device and properly configured by the Direct IO manager of the        target device, the smart input I/O unit controller is capable of        receiving the content from the smart personal device and deliver        the content directly to the output I/O unit controller using the        I/O BUS independent of the Core Media Processor and Main Memory.        In addition, in this embodiment of Direct I/O method, the Core        Media Processor and Main Memory can be turned off or to be in a        low power sleep mode thus significantly reducing power required        for the operation. This Direct I/O method may be enabled in        devices including but not limited to HDTV, Music systems,        Personal Computers or target device comprising at least one        smart Input unit controller, one smart storage unit controller        and one smart output unit controller.    -   In another embodiment, when the smart personal device is leaving        one target device and arriving at a different target device, the        smart personal device upon detection of it is no longer        proximate to the first target device it will automatically store        the content in a temporary buffer or storage unit and suspend        the content delivery to the target device by marking or        bookmarking the current position using the intelligence on the        smart personal device unit. Upon identifying a new target device        or back to the original target device located proximate to the        smart personal device, it will first deliver the content from        its temporary buffer or storage unit therefore there is no        interruption or loss of the content while the user is        transitioning from one target device location to the next by        resuming the content delivery from the previously marked or        bookmarked position.    -   The present invention describes content delivery from the smart        personal device to a first HDTV target device and redirect the        content to a second HDTV target device whereby the target device        located proximate to the smart personal device. In another        embedment of the present invention the smart personal device is        receiving a live digital FM broadcasting contents while        delivering the FM broadcasting contents to a digital speaker        system (Target device #1) in a home location on network #1. When        the user is leaving the above described home location and        entering in a second location i.e. an automobile with a digital        speaker system, the smart personal device will first deactivate        the first target device on network #1 when the first target        device is no longer proximate to the smart personal Device (the        first time), automatically start storing or recording the        content from the FM broadcasting on its storage unit. Upon        identifying the digital speaker system (Target device #2) in the        automobile on network #2 located proximate to the smart personal        device (the second time), it will activate the target device #2        and resume the content delivery from the previous stored content        while continuing storing or recording the current FM        broadcasting content. In the above embodiment, the network #1        whereas the smart personal device and the target device        communicate by means may include but not limited to a wireless        Ethernet network. However the network #2 is a different network        from the network #1 whereas the smart personal device and target        device #2 communicate by means may include but not limited to a        Bluetooth network.    -   In yet another embodiment, the smart personal device upon user's        selection is capable of waking up one of more target devices        from the low power sleep state and performs content search        operation of its neighboring target devices which has been        enabled for such actions. Once the matching criteria is found,        the smart personal device will “pull” such content from its        neighboring target devices and store on the local storage of the        smart personal device without interrupting its current operation        of either device. The transfer of the content can be performed        using the CPU, memory and the I/O BUS of the neighboring target        devices, or if the neighboring target device comprises smart I/O        controllers, the transfer of content can optionally be performed        using a Direct I/O method of transferring content from the smart        storage unit I/O controller to the smart network unit I/O        controller independent of the target device's CPU and memory.        i.e. under the program control of its Direct I/O Manager,        content is transferred from the smart storage unit I/O        controller to the network unit I/O controller using the I/O BUS        independent of its CPU and main memory. Then the network unit        I/O controller transfers the content to the storage unit I/O        controller of the smart personal device. The smart personal        device with the smart I/O controller have the option to directly        transfer the content from its smart network unit I/O controller        to the smart storage I/O unit controller independent of its CPU        and main memory operate effective under control of the Direct        I/O Manager. The Direct I/O method improves the speed        performance and reduces power consumption of the device since        the CPU and main memory are not active during the content        transfer operation. Upon completion, the smart personal device        will alert the user that such contents are ready for display at        user's convenience.    -   In yet another embodiment, the present invention may, upon its        user's command, using “pull” method amongst neighboring target        devices as well as content host target devices across the        internet; instead of having contents, such as web        advertisements, being “pushed” onto the smart personal device        without the consent of the user, the smart personal device will        operate effectively to block all non-authorized intrusive        contents from displaying on the smart personal device or target        devices without the consent of the user; instead it offers user        an option to specify a desire content criteria for the smart        personal device to perform search directly, or indirectly        through another intermediary web based service on user's        specified criteria. Once the relevant criteria are found, a        matched content list will be generated by the smart personal        device to enable the user to review the list at one's        convenience. If the user elects to view one or more (or all) of        the match content from the list, the smart personal device is        operable effective to PULL the selected content from the storage        area of the various content hosts, which may be over the        Internet or target device in its LAN environment. After the        completion of the PULL steps, content such as web advertisement        is stored onto the storage I/O unit controller of the smart        personal device for display at user's convenience. The present        invention using “pull content” method for web advertisements        over internet as an example, such invention may apply to a        variety of contents over the Internet including but not limited        to pull relevant books content, relevant news content, relevant        sales contents, relevant advertisement promotion through the use        of banners, widgets, etc. and user-specified web target services        and information sources including but not limited to google.com,        facebook.com, youtube.com, amazon.com, uspto.gov, etc.    -   DEACTIVATION: When the smart personal device is no longer        proximate to the target device, the target device will        automatically be deactivated by the smart personal device in the        present invention so the underlining data processing logic        including but not limited to the media CPU, main memory, input        and output controllers and associated input and output devices        and resume in a low power sleep state. Once the target device        enters in the low power sleep state the only function running        under the low power sleep state is the activation detection        logic comprising, but not limited to, RFID, proximity sensor,        wake on LAN, and wake on USB units. In one embodiment of a        related invention, the target device performs the role of        deactivation whereby the target device identifies a smart        personal device is no longer located proximate to the target        device and performs all operations to deactivate the underlining        data processing logic including but not limited to the media        CPU, main memory, input and output controllers and associated        input and output devices and resume in a low power sleep state.
